Electrical Panel Replacement & Upgrade in Kansas City, MO
Kansas City's housing runs from 1920s bungalows to brand-new Northland builds, and the panel behind the cover tells you which era you're standing in. We replace fuse boxes in Waldo and full 200-amp services on new construction, and the job looks nothing alike.
A different panel on every block
In Brookside and Waldo we still find knob-and-tube remnants feeding a panel that was upgraded once in the 1970s and never again. Around Westport and the Crossroads, converted and subdivided buildings often have service that was never properly re-sized for how the space is used now. Newer Northland construction usually has capacity but sometimes no free slots. The one constant across all of it: nobody regrets going to 200 amps, and plenty of people regret not doing it while the wall was open.
What an electrical panel replacement costs in Kansas City
Most contractors won’t tell you what sets the price until they’re standing in your house. Here’s what we look at, and which parts actually move the number.
| Job | Relative cost | What drives it |
|---|---|---|
| Like-for-like 100A replacement | Baseline | Same service size, safer panel. |
| 100A → 200A service upgrade | Higher | New panel, meter socket, and service entrance conductors. |
| Fuse box or knob-and-tube era | Highest | Older Brookside and Waldo homes. Mast, grounding, and sometimes branch circuits need bringing up to code. |
| Sub-panel addition | Lowest | Detached garages, basement apartments, workshops. |
Older housing is where the variation comes from — if the mast, meter socket, and grounding all need replacing alongside the panel, that's the most involved version of this job. We price it flat after seeing it.

Questions We Get in Kansas City
How much does it cost to replace an electrical panel in Kansas City?
Same-size replacements are the least involved. A 100A to 200A upgrade costs more, because the meter socket and service entrance conductors change with it. Older homes in Brookside or Waldo with a fuse box or knob-and-tube wiring run highest — the mast, grounding, and sometimes branch circuits need work alongside the panel.
Do I need a 200 amp service?
If you have central air, electric appliances, and any plans for an EV charger or hot tub, almost certainly. If you're in a small home with gas heat and no plans to add load, 100A may still be fine. We'll give you the honest answer.
What's wrong with knob-and-tube wiring?
It has no ground conductor, the insulation degrades over decades, and it was never designed for modern loads. Many insurers won't write a policy on a house that still has active knob-and-tube circuits.
How long will my power be out?
Typically four to eight hours, in a window coordinated with Evergy ahead of time.
